Rhubarb and Ginger Cake
Ingredients
Directions
Prepare
Preheat the oven to 180 °C (350 °F, Gas mark 4).
Trim the leafy tops and pale pink root slivers from the rhubarb stalks, then rinse and chop the rhubarb into 1‑inch (2 cm) chunks.
Make the cake
Cream the butter and sugar together until light and fluffy; add the eggs one at a time, beating well after each addition.
Fold in the flour and ground ginger.
Spoon the batter into a greased and lined 8‑inch tin.
Spread the prepared rhubarb over the batter and sprinkle with sugar.
Top and bake
Make the topping by rubbing the butter into the flour until it resembles breadcrumbs, then stir in the sugar.
Spoon the topping over the rhubarb.
Bake for 3/4 hour until firm and springy to the touch.
Allow to cool and dust with icing sugar before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides tart fruit flavour and moisture that bakes into the cake.
- Butter
- Adds richness and tenderness through fat that coats the flour.
- Eggs
- Bind the batter and help it set firm while adding structure.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Ground ginger
- Adds warm, spicy aroma that complements the tart rhubarb.
